Is the Ozone Layer on the Mend? Highlights from the most recent WMO/UNEP Ozone Assessment
Bulletin, Vol. 64(1). WMO, 2015The 2014 Ozone Assessment provides the latest update of the current state of the ozone layer and makes predictions on when the ozone layer will return to 1980 values. In the northern middle latitudes (35-60°N), total ozone is now about 3.5% less than it was in the period from 1964-1980. At southern middle latitudes (35-60°S), it is about 6% less. The larger depletion in the Southern Hemisphere is linked to the Antarctic ozone hole. Following the decline in total ozone during the 1980s and 1990s, the situation has stabilized since 2000. Hidden under the inter-annual variability, there are indic ...

EEA, 2013Aggregated data reported by companies on the import, export, production, destruction and feedstock and process agent use of ozone-depleting substances in the European Union – SUMMARY
Monitoring the Climate System with Satellites
The international science community has identified a set of Essential Climate Variables (ECVs) that should be monitored for measuring the climate system, how it is changing, and its likely impact on future climate. Environmental satellites play an important role in this effort. They are uniquely positioned to provide broad, spatially consistent, and continuous global sampling of many of the ECVs. This module explores the benefits of monitoring the climate system with satellites. We begin by reviewing how satellites observe key atmospheric elements and features that are found in a variety of cl ...

Air & Climate: conversations about molecules and planets, with humans in between
European Commission, 2012This is a collection of conversations with some of the ‘fathers’ of air pollution and climate change science. Through careful observation and a mix of intuition and critical thought, they have uncovered some of the workings of our planet: its atmosphere and climate. They were generally driven by curiosity and gradually by a concern that mankind might indeed have a devastating impact on Earth and the life it hosts. Their findings were so important that they could not stay in the ivory tower of scientific research. They personally reached out to decision makers and the public at large because in ...

Evidence for the effectiveness of the Montreal Protocol to protect the ozone layer
Atmospheric Chemistry and Physics (ACP), Vol. 10. N° 24. Mäder J.A.; Staehelin Johannes; Peter T.; et al. - Copernicus GmbH, 2011The release of man-made ozone depleting substances (ODS, including chlorofluorocarbons and halons) into the atmosphere has led to a near-linear increase in stratospheric halogen loading since the early 1970s, which levelled off after the mid-1990s and then started to decline, in response to the ban of many ODS by the Montreal Protocol (1987). We developed a multiple linear regression model to test whether this already had a measurable effect on total ozone values observed by the global network of ground-based instruments. The model includes explanatory variables describing the influence of var ...
